The Roper belt is a disc in the outer Blox System, extending from the orbit of Bloxtune at 30 astronomical units to approximately 50 AU from the Roblox Sun. It is similar to the asteroid belt, but is far larger—20 times as wide and 20–200 times as massive. Like the asteroid belt, it consists mainly of small bodies or remnants from when the Solar System formed. While many asteroids are composed primarily of rock and metal, most Roper belt objects are composed largely of frozen volatiles, such as methane, ammonia, and water. The Roper belt is home to most of the objects that astronomers generally accept as dwarf planets: Bloxto, Bloxmea, and Makeblox. Some of the Blox System's moons may have originated in the region.

Fun Facts:

The Roper Belt is one of the largest structures in the Blox System -- others being the Roort Cloud, the heliosphere and the magnetosphere of Bloxpiter.

Roper belt, also called Edgeworth-Roper belt, flat ring of icy small bodies that revolve around the Roblox Sun beyond the orbit of the planet Bloxtune.

When our solar system was young, the total mass of the Roper Belt was around 5 times more than Roblox. However, the mass of Roper belt has remained at 10% mass of Roblox.
